MANUFACTURE OF RUBBER snons.

Specification of Letters Patent.

Patented Dec. 12, 1911'.

Application filed February 11, 1911. Serial No. 607,894.

To all whom it may concern:

Be it known that we, PATRICK KANE and AsA BELKNAP GRIGcs, both residents of Granby, in the Province of Quebec, in the Dominion of Canada, subjects of the King of Great Britain, have invented certain new and useful Improvements in the Manufacture of Rubber Shoes; and we do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in objects of the invention are to simplify the method of turning out the shoes and so cheapen the cost of production and to provide a serviceable article that will give better satisfaction to the wearer, and it consists essentially in the novel arrangement and cut of the upper and the manner in which the tongue is secured thereto as more particularly described in detail hereinafter and pointed out in the claim.

In the drawings, Figure 1 is a perspective view of the finished shoe. Fig. 2 is a plan view of the upper. Fig. 3 is a plan view of the tongue.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the toe? portion of the upper, 2 the vamp, 3 the counters and 4 the instep, all formed in the one piece as illustrated in Fig. 2, the counter portions 3 extending around and meeting at the back.

5 is an incision at the instep portion 4 extending downwardly into the vamp 2 at one side of the center line of the instep, vamp and toe portions.

6 is the tongue adapted to form what is known as a pocket tongue.

In carrying out the manufacture of this shoe, the tongue of rubber or rubbered material is adhered to the inner side of the instep portion and extends down to the innor side of the vamp portion, said tongue being folded in at each side in the customary Copies of this patent may be obtained for five cents manner. The upper, while on the last, over the lining, is worked over on the instep portion from the one side of the incision until there is quite an over-lap, as shown at 7 in Fig. 1. This over-lap is held in that position during the curing by the buckles 8 or other fasteners. It will be thus seen that an exceptionally good waterproof shoe is attained in this construction, for ordinarily in the manufacture of these shoes, the front opening is central and the edges of the in step portion from each side just meet and are held together by the usual buckles, but in walking in slush or deep snow, the rubber of the instep portion bends in folds consequently opening the way into the pocket tongue, with the result that a collection of snow and ice and other slush gathers in the front of the shoe and eventually ruins thev footwear at that point, besides being extremely uncomfortable. In the present invention, the overlap completely overcomes such difficulties as the shoe cannot open at the front at all and this is accomplished by the working over of the rubber from one side of the incision and doing this while the tongue is already in place in the inner side of the upper.

What we claim as our invention is:

The herein described method of producing a rubber overshoe having an overlap ping instep opening, consisting in slitting the upper to provide said opening, and stretching the material on one side the opening over the material of the other side while on the last and previous to the curing of the rubber, and suitably holding the material stretched during the curing.
